Reoperation for degenerated mitral bioprosthesis is considered a high risk procedure. Transcatheter mitral valve in valve implantation has emerged as an off-label alternative for patients contra-indicated to surgery. We report a 46-year-old man, with a 29 mm mitral bioprosthesis since 2002, who was admitted for acute heart failure because of a severe intra-prosthetic regurgitation. His recent medical history revealed a fast growing cavum carcinoma. In view of generally poor prognosis, the heart team decided to perform a transcatheter mitral valve in valve implantation by transapical approach. Live three-dimensional TEE was used during the implantation for sizing, device positioning, and hemodynamic assessment.
